RELEASING DEVICE FOR STALLS.

Specification of Letters fatent.

Patented Dec. 4, 1906.

Application filed December 1,1905- Serial No. 289.903.

To all whom it may concern:

Be it known that I, ADDISON G. DUNHAM, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Releasing Devicesfor Stalls, of which the following is a specification.

My invention relates to an automatic releasing device for horse-stalls.

The features of the invention are more fully set forth in thedescription of the accompanying drawings, forming a part of thisspecification, in which 4 Figure 1 is a front elevation, partly insection, of my improved releasing device for stalls, showing threestalls. Fig. 2 is an enlarged section on line w m, Fig. 1. Fig. 3 is anenlarged planview of one of the locking-bolts. Fig. 4 is an enlargedsection on line w w, Fig. 1.

1 2 3 4 represent the walls of the stalls.

5 represents the mangers, having the orifices 6.

7 re resents a U-shaped arm in each stall, slidab y supported by thestaples 8, secured in the manger. These arms 7 are connected by a cableor wire 9, which passes through the walls of the stalls, one end of thecable being connected to a releasing-lever 10 outside of the stable,say, and the other end of the cable 9 is attached to a tension-spring11, which holds the arms normally through the staples 8 and bridging theorifices 6.

12 represents the fastening-chain, having the anchor-clip 13 inside ofthe manger extending across the inside of the orifice 6, the chainpassing from the inside of the manger out through the orifice 6, aroundthe upper end of the arm 7, and back into the manger again.

In operation it is obvious that when the lever 10 is manipulated the arm7 can be withdrawn from the staples 8 to release the chain 12 and thatall the chains will be freed from their attachment to the mangers whenthe lever 10 is manipulated.

It is also desirable that when the releasinglever 10 is thrown back thatit will be nor mally locked in such position in order to hold the arm 7free from the orifices 6. This is accomplished by the followinginstrumen talities: 14 represents a U-shaped bracket, between the limbsof which the lever 10 passes. 15 represents lips extended inward, theends of which form a shoulder, so that when the lever has assed the samethey will form an abutment or the lever, holding the same in its openposition.

It is also obvious that the halter or chain 12 can be secured to the arm7 in various manners, in which a release can be effected. by a movementof the arm.

Having described my invention, I claim In combination with a series ofmangers each having an orifice, a series of staples, a series ofU-shaped arms sliding in said staples, one of each of said arms bridgingone of each of said orifices, a series of wires connecting the saidseries of arms, a spring attached to one of the wires at one end and alever attached to the wire at the opposite end, substantially asdescribed.

In testimony whereof I- have hereunto set my hand.

ADDISON G. DUNHAM.
